Hi all,
I have data as below. First column is time column. The second column is x values and the third column is y values. I want to plot this data.The data shows that a round ball is at the x and y location at given time. This ball seems to be shifting/rolling. How can I plot this movement of the ball? The data is as follows.
Thanks.

@Cem Eren Aslan, you can use plot function handle and delete it at end of every iteration inside the loop,
data = [0 0 0

You can use the plot function in MATLAB for simple visualization of the given 2D trajectory.
You can refer the following MATLAB Documention for more information on plot function: www.mathworks.com/help/matlab/ref/plot.html
Moreover, to visualize the movement over time you can use the loop to draw the position of ball at each time step. You can do something like this to visualize the movement:
for i = 1:length(x)
plot(x(i), y(i), 'ro', 'MarkerFaceColor', 'r');
pause(0.1); % Adjust the speed of animation by changing the pause duration
end
